I wrote this a a few years ago for my website that I have now migrated to wordpress.

Soon after Google Latitude started I signed up for it and sporadically updated my location. This worked slightly better with more advanced phones, but until I got my hands on a Nexus S in Autumn 2010 this always stayed very patchy. Just before Christmas 2012 a friend pointed me to Google Takeout that allows to download all data Goggle has stored about you including the Latitude data, if you have signed up for it. I had previously wondered how I could display my annual travel and had dabbled with the possibility to download parts of my entire in kml format form within Latitude. This however looked like it would make the whole project much simpler. So, I downloaded my data and thought I would quickly make a little map.

The first disappointment was that the takeout data was in json format and looking at it was not easy … After searching around for a while I found this script that converted json to kml. At last I could see my track in Google Earth. Unfortunately, Latitude includes quite a bit of erroneous data. So, the next step was to find a program that allows to edit a gpx trace. Again, it took a while to find the right program that I liked, eventually I found gpsprune . Now, the problem was that the entire annual data was a bit large. I used gpsbabel to break down the data into days.

The final product still has a few glitches which are mainly due to me being a bit slow to switch on data roaming or because Latitude failed (I believe there are a few days in 2012 where this was the case for my account).
